GENERAL DESCRIPTION
The AD9235 is a family of monolithic, single 3 V supply, 12-bit, 20/40/65 MSPS analog-to-digital converters (ADCs). This family features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9235 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 20/40/65 MSPS data rates and guarantee no missing codes over the full operating temperature range.

FEATURES
    Single 3 V supply operation (2.7 V to 3.6 V)
    SNR = 70 dBc to Nyquist at 65 MSPS
    SFDR = 85 dBc to Nyquist at 65 MSPS
    Low power: 300 mW at 65 MSPS
    Differential input with 500 MHz bandwidth
    On-chip reference and SHA
    DNL = ±0.4 LSB
    Flexible analog input: 1 V p-p to 2 V p-p range
